IMPROVEMENT IN BE'LT-FASTEN ERS.

Specification forming part of Letters Patent No. 189,988, dated April24, 1877; application filed A February 22, 1877.

To all whom it may concern:

Be it known that I, JOHANN BAOHMANN, of Nrnberg, Germany, have inventeda new and useful Improvement in Belt-Fasteners, of which thefollowingisa description, reference beinghad to the accompanyingdrawing, forming part of this specification.

The invention relates to metallic fastenings for joining the ends ofbands or belts, and by the use of which not only time and labor areeconomized. but material also, by dispensing with that overlapping ofthe ends of the belt which is necessary when said ends are lacedtogether-said metallic fastenings to give a better hold of the belt onits pulleys.

The invention consists in a metallic belt fastener or fastening composedof hinged sections, each ofwhich is formed with a tongue or tonguesprojecting beyond the joint-pin of the hinge on the opposite side of thesaid pin to that on which the body of the same section projects, therebyforming a double crossclamp, the inner surfaces of which are providedwith teeth, and which, when closed, clamp both ends of the belt on itsreverse or opposite sides. This not only forms avery secure fastening,but also one which may be very readily attached to and detached from theends of the belt.

Figures 1 and 2 represent back and face views of a belt-fasteningconstructed in accordance with the invention, and Figs. 3 and 4 endviews of the same in its open and closed positions.

A B are the hinged sections of the fastening. These sections areconstructed with tongues fg, which extend beyond or to oppoends ofthebelt, and each hinged 'belt-fasten ing section A B is provided, bothas regards its main body and tongues, with sharp or penetrating teeth,b, which stick into the belt ends, the teeth on the tongues fg beingimmediately arranged in relation withthe teeth on the bodies of thesections which said tongues face when the fastening is closed, as

shown in Fig. 8. When the fastening is opened, as shown in Fig. 7, everyfacility is afforded for entry or removal of the ends of the belt whichit serves to secure.

I claimrIhe cross or double-clamp fastening, composed of hinged sectionsA B, each of which has one or more tongues, f g, projecting beyond thejoint-pin of the hinge on. the opposite side of said pin to that onwhich the body of the same section projects,'the bodies and tongues ofsaid sections being provided with intermediately-arranged teeth b, allsubstantially as shown and described. l

In testimony that I claim the foregoing I have hereunto set my hand this16th day of December, 1876.

JOHANN BAOHMANN.
